I took a drive out to a fairly local reservoir near Addingham in Yorkshire. The reservoir is called Chelker Reservoir and has four wind turbines sat on one of the banks, unfortunately only two had the actual blades atached and the other two were being serviced I imagine. Hopefully next time I head up there the turbines will be all fully functioning so I can get a bit of movement from the blades using the ND4 and Circular Polarizer.
